- cupy.trace(a, offset=0, axis1=0, axis2=1, dtype=None, out=None)[source]#
Returns the sum along the diagonals of an array.
It computes the sum along the diagonals at
a (cupy.ndarray) – Array to take trace.
offset (int) – Index of diagonals. Zero indicates the main diagonal, a positive value an upper diagonal, and a negative value a lower diagonal.
axis1 (int) – The first axis along which the trace is taken.
axis2 (int) – The second axis along which the trace is taken.
dtype – Data type specifier of the output.
out (cupy.ndarray) – Output array.
